I was trying to build something like that myself, but I had based it off IRC and was going to go protocol first not PaaS type of thing.

I think this is an unclaimed space where the future of work is bound to find itself in, though I'm not yet sure how/who is gonna win.

My solo project was abandoned unfortunately, that said I saw some cool protocol initiatives similar to it recently like this one: https://github.com/h5i-dev/h5i
